Immersion inspection systems

Immersion ultrasonic testing (UT) systems are advanced inspection solutions in which both the test component and the ultrasonic probes are placed in a water-filled tank that serves as the coupling medium. This setup provides exceptionally stable conditions for ultrasonic wave propagation, resulting in high signal quality, repeatable measurements, and the ability to inspect components with complex geometries. Water as the couplant eliminates the need for gels or point-applied liquids, ensuring uniform acoustic coupling across the entire surface of the inspected part.

Immersion systems are used in both conventional UT examinations and advanced techniques such as Phased Array and FMC/TFM. They may be equipped with multi-axis positioning tables, manipulators, or robots that enable full, automated scanning of objects such as forgings, castings, aerospace components, automotive parts, and composite laminates. The system software allows the creation of defect maps, cross-section analysis, thickness measurements, documentation of results, and integration with production management systems. Thanks to their precision, flexibility, and high sensitivity to material discontinuities, immersion UT systems are among the most effective tools for ultrasonic non-destructive testing in industrial applications.
